Operation and Maintenance RRU OAM • The ZXSDR R8972 configures RRU in accordance with configuration data, forwards RRU’s management commands from the NetNumen U31, and collects RRU’s alarm and performance information. SON Functions • SON functions can help perform some network planning, configuration, optimization, and healing processes automatically, and lower OPEX by reducing manual involvement in such tasks.
